Brief summary
The primary objective of this study is to determine the safety and tolerability of multiple doses of QRL-201 in people living with ALS
Detailed description
This first-in-human, Phase 1 study will evaluate the safety, tolerability, and pharmacokinetics (PK) of QRL-201 administered intrathecal (IT) to participants with Amyotrophic Lateral Sclerosis. Two dose escalation cohorts of 8 participants each, followed by an additional 48 participants, receiving the study drug in a 6:2 ratio of QRL-201 to placebo.
Interventions
Multiple ascending doses of QRL-201 will be intrathecally administered to individuals with sporadic ALS.
Multiple ascending doses of placebo comparator will be intrathecally administered to individuals with sporadic ALS.
QRL-201 will be intrathecally administered to individuals with C9orf72 ALS.
Placebo comparator will be intrathecally administered to individuals with C9orf72 ALS.

Masking description
Multiple-ascending doses of QRL-201 or placebo will be administered. The dose levels may change subject to available nonclinical, clinical, safety, and PK data.
